What should I do?

One of my favorite games is coming out in November, which is Dragonball Z Budokai Tenkaichi 3, but I'm not sure which system to get it for. I've always played it on the PS2 but I want to see how it plays on the Wii. I'm kinda stuck inbetween. Do I keep with the old controls on my PS3 or do I try something new with the Wii? How are the controls for the Wii anyways, and is it as intense on the Wii as it is for the PS2?
